It's always too early to quit.

Know or listen to those who know.

What you do today can improve all your tomorrows.

Go for it now. The future is promised to no one.

The wise does at once what the fool does at last.

If you can dream it, you can do it.

Who seeks shall find.

Be thine own palace, or the world's thy jail.

The secret of getting ahead is getting started.
